Product Overview

This multi-functional sealing anti-loosening screw integrates a sealing element under the head, with a high-strength structural body; when tightened, the seal automatically fills the mating-face gap to form a waterproof, dustproof barrier. Combining fastening, sealing and cushioned anti-loosening in one, it suits holes that must both carry load and seal, reducing part count and leak points.

Technical Features

• An integrated under-head seal means tightening seals the joint, with no extra gasket.
• The seal fills gaps automatically under pressure, tolerating some flatness deviation.
• Built-in cushioning absorbs part of the vibration energy
• One part handles both fastening and sealing, cutting leak points and assembly steps
• Seal material and hardness are customised to drawing requirements.
